It derusts chrome well.
1 gallon to a pound of oxalic acid works well. Honestly half of that works well. This is what I use to derust bare cast iron car parts so unless your bike looks like that I would not go any stronger and in fact would go half.
$h1t will start going south not on the strength of your solution but on leaving it there longer than it needs to. Soak it, gloves and a rag to work it in, then take it out and wash it. You can leave the parts soaking overnight but then again that's what can hurt the stickers.
Watch out for bronze and copper, it will clean them well but if left overnight a nasty film will build up on everything else.
